Application filed uly v26, 1900. Serial No. 24.924. iNo model.)

To a/ZZ whomv t may concern:

. Beit known that I, FRIDoLIN SGHIFFERLE, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and `useful Improvements in Water- Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in water-heaters; and it consists in the novel arrangement and combinationof parts more fully set forth in the specification and pointed ont in the claims.

In the drawings, Figure 1 is a top plan view ofthe heater. Fig. 2 is a section on line 2 2 of Fig. 3, showing top of the burner. Fig. 3 is a middle vertical longitudinal section on line 3 3 of Fig. 1. Fig. 4 is a transverse section of a bath-tub, showing my heater in end view and partly submerged under water in the tub, this igure showing a side view of the straddle-bar by which the heater is held down in the tub; and Fig. 5 is a detached plan view of the straddle-bar.

The present invention is an improvement on the heater shown and describedin United States Letters Patent issued to me under date of May 8, 1900, numbered 649,111, and has for its object to increase the efficiency over the patented device and in a measure simplify the construction of the parts connected' directly with the burner and, furthermore, to improve the device in particulars, the several advantages of which will be more apparent from a detailed description vof the invention, which is as follows:

Referring to the drawings, l represents a hollow casing of any convenient shape or configuration, the same being provided at one end with a series of air-inlet ues 2, projecting from the top or roof of the casing and extending a suitable distance below the said roof to effect a better distribution of the inowin g air within the casing. Located along the medial longitudinal line of the casing and between the Iiues 2 is a tube 3 for the reception of the feed-pipe 4, coupled to the burner 5, mounted inside the casing. In the present device the feed-pipe 4 is connected to the gas tube or hose through the medium of a coupling 7 of the form of an inverted cup, the

base of said cup being provided with a nozzle 8, to which the hose 6 is directly attached, and with air-openings 9 around the base of the nozzle for the ad mission of the necessary quantity of air to insure a mixture which will result in perfect combustion when a match or light is applied to the burner. The latter is composed in the preseutinstance ofaclosed pan or casing surmounted by a cover-plate provided with transversely-cut parallel slits 5", through which the flames issue, the close proximity of the several sheets of liame to one another resulting in one sheet of ilame over the entire surface of the cover-plate and producing intense heat. The escape-due l0 is at the opposite end of the casing and may be of any desirable height. The coupling or cup '7 is of such a diameter that it may be readily inserted into the tube 3 and embrace the pipe 4, the parts being then united by a screw 11, which passes through alining openings formed in the tube 3 and cup 7, the inner end of the screw bearing against the piper4.

Depending from the top of the casing, directly in front of the escape-flue 10, is a deecting wall or plate 12 for the purpose of temporarily intercepting or retarding the prod- ,ucts of combustion and hot air in their escape from the casing.

The present device is provided with a handle 13,having a centrally-depressed or concave portion adapted to form a support for a yielding (preferably) wooden straddle-bar 14, adapted to be placed across the heater, with its opposite ends frictionally engaging the sides of the tub l5, in which the heater is partially submerged. To insure a maximum degree of contact between the tub and bar, the ends of the latter are provided with rubber caps or tips 16. The straddle-bar serves to hold the heater down in the water and keep it from iioating or displacement after being once setin the tub. On one side of the handle is disposed a tube 17, the base of which opens above the burner, the said tube being adapted to receive a lighted stick or taper (not shown) for igniting the burner. The tube is closed by the hinged cover 18. On the opposite side of the handle is a tube 19, at the bottom of which is pivoted a transparent lid or door 20, (preferably of mica,) the said door being normally held in a closed position by a wire IOO handle 21, the upper of which is forced under a lip 22, carried by the Wall of the tube 19. The transparent door is for the purpose of permitting inspection of the burner from lthe top of the casing and when the door is opened (see dotted position, Fig. 3) maj7 also serve to permit the insertion of a taper for purposes of lighting the burner.

Itis of course apparent that the present construction may be departed from in a measure without aiecting the spirit of the invention. For example, while I have shown only two air-inlet flues any other number might be employed. So might I use more than one escape-flue. It is also apparent that the depth to which the air-inlet filles extend below the roof of the casing may be varied.

It will be observed that in the present device the coupling 7 is devoid of any cocks or valves, this arrangement simplifying the construction,since the gas is controlled only from one point-that is, from the fixture, to which the opposite end of the hose 6 may be attached.

Having described my invention, what I claim is 1. A water-heater comprising a hollow casing, a series of air-inlet fines and an escapeflue leading from the same, a burner confined within the casing, a feed-pipe for the burner, a tube carried by the casing and inclosing the feed-pipe, a coupling or cup inserted between the adjacent walls of the feed-pipe and inclosing tube respectively, the walls of the coupling serving to seal the opening leading to the space between the said feed-pipe and inclosing tu be therefor, means for holding the couplingin position, a central nozzle projecting from the base of the coupling, the latter being provided withv air-openings around the base ofv the nozzle for the free admixture of air with the gas delivered through the nozzle, substantially as set forth.

- 2. In `a water-heater, a suitable casing, a

handle therefor, and a straddle-bar adapted to be placed across the casing against the handle, the free ends of the bar frictionally engaging the sides of the tub, substantially as set forth.

3. In a water-heater a suitable casing, a

burner located within the same, an open tube projecting from the roof of the casing, a transparent door or lid hinged at the bottom of the tube, a wire handle secured at one end to the door, a lip carried by the wall of the tube for thepreception of the free end of the handle whereby the door is held in a closed position, substantially as set forth.

4. A water-heater comprising a casing, a series of air-inlet fines disposed at one end thereof on either side of the medial longitudinal line of the casing, a tube projecting from the casing between the air-inlet fines, a feedpipe inclosed by said tube, a burner located in the casing and coupled to the feed-pipe, a

cup effecting a union between the upper endsV of the feed-pipe and inclosing tube and sealing the opening leading to the space between the feed-pipe and inclosing tube, a nozzle forming a part of said cup the latter being provided with air-openings around the base of the nozzle, an escape-flue at the opposite end of the casing, a deiiecting wall or plate depending from the roof of the casing in front of the escape-liuc, the air-inlet lines extending a suitable distance into the casing to effect a better distribution of the air conveyed by them into the casing, and a tube projecting from the roof of the casing for the reception of a lighted stick or taper, substantially as set forth.

In testimony whereof I alix my signature in presence of two witnesses.
